Weaponize bacteria -> abolish antibiotic-resistant superbugs?

I suspect that this would just be the next step in the weapons race between humans and bacteria - one which I don't see humans winning as such. But I like the idea here of turning bacteria against each other, especially since the "good" bacteria will also evolve, hopefully saving scientists some work.

Hypothetically, it could be possible to engineer an army of “good” bacteria equipped with T6SS and send them to war against dangerous bacteria like A. baumannii—similar to what happens naturally with bacteria in the human gut. In another scenario, it could be possible to target the drug-resistant A. baumannii strains to force them to activate their T6SS weaponry, which would then cause them to lose antibiotic resistance and theoretically make the infection treatable.
